2, 8, and are thereby securely housed and protected from sleet,s1mw andany other danger that` might threaten to interfere with the freeoperation thereof. These members may be ot any suitable material but arepreferably ot metal and have a sliding tit. in said tracks and theyserve to carr v and guide the cleaner across the glass. These carriersmay, if desired. see Fig. be provided with roler or ball bearings 7, butit is not necessary.

The cleaner, Figs. 1 and 3, may comprise a back 9, preferably in theform ot' a long, narrow member, provided at one face with a narrowlockingr strip 10, secured thereto as by screws 1l, to lock between saidback and said locking strip a cleaner l2, ot` i'elt, rubber or anysuitable material. Said cleaner 12 may be provided with laterallyextending solts 13 so that it may be adjusted to or from the glass asrequired. To secure said cleaner to the carriers T, 8, we providehangers 14, 15, which may be secured to the back t) by screws 16, slots17 in said hangers permitting longitudinal adjustment thereof, ifdesired, relative to said back. The upper hanger 14 extends through alongitudinal slot or aperture 18 in the under side of the guide or track2 and is received by a slot in the lower side oi" the carrier T, whereit is shown, Fig. 3, secured by a scre\v 19. This screw' may be readilyinserted and removed by sliding the carrier along the guide toward theright until the head of the screw is opposite the opening 20 in the rearlside of the guide 2, which permits a screw driver to bc inserted forthat purpose. The lower hanger 15 is hook-shaped in form herein, alsoextends upwardly through a longitudinal slotor aperture 21 in the lowerside of the guide 3 and enters a similar slot in the cari-1er 8 where itmay be secured, if desired, but it is not necessary as it cannot becomedetached from the carrier 8 without first detaching the upper hangerfrom its carrier 7. In order to actuate said carriers to operate thecleaner we may secure to the ends of said carriers, by any suitablemeans, as herein by eyes 22, cords, chains or similar members 23, whichmay be counter-sunk in the ends of the carrier if desired to make thearrangement compact, carried over rolls 24, Fig. 4, at the ends of theguides 2, 3, .and herein mounted in said guides and thence "through thethence,1Fig. 4:, over rolls or pulleys 25 se- To all whom it may conce/aBe it known that we, Ernest-1 l. Lanus and FREDERICK C. Romxsox,citizens ot the and residents ot Portnind. liu l the county ofCumberland and Slate ot Maine, have invented an VImprovement in'VVindowCleaning Devices, of which the following decription, inconnection wit-h the accompanying drawings, is a speciticatitm, likeletters on the drawings representing like parts.

Our invention relates to window cleaning devices, and more specificallyaims to provide an improved window cleaner for use particularly onelectriocars, motor cars, pilot-housesoi Steamers and similar placesUnited States,

from the glass rain, snow, sleet, dust, etc.

In the drawing showing an illustrative embodiment of our invention asapplied to a conventional form ot window, as, tor iustance, a window ota vestibuled electric ear, Figure l is an elevation ot' the out-side ofsuch a window with our improved attachment secured thereto, partsthereof being roken away; Fig. 2, an elevation ot' the inside of saidwindow. parts oi the frame beingl broken away; F a vertical section onthe line 3-3 Fig. l; Fig. 4tan enlarged section detail on the line 4-4Fig. l, looking down; Fig. 5 illustrates various modiications of thesupporting guide or track; and Fig. 6 a moditication ot the carrier.

Referring first to Fig. 1, the window frame lpis` provided at twoopposite edges thereof, and herein at its top and bottom, 'with guidesupports or tracks 2, 2?, herein shown as hollow, tube-like members,secured, Figs. land 4, at their ends to posts Ll, se` cured in turn bymeans of plates 5, to the frame 1. The posts and plates ."i may, forconvenience, be constructed integral with each other. The members 2, i5,may be tubuiar, or they ,may be llat plates rolled inte substantiallytubular form, or they may be ot' any desired form in cross-section, seeFig. 5, and may, Fig. 4be simply received in apertures in the posts 4t,or they maybe 'threaded therein or otherwise secured thereto. The posts4 are drilled, or otherwise provided with passages therethrough, andsaid passages are adapted to register with apertures 6 through thewindow trame. `Carriers or carriages 7, 8, of suitable form, and whichherein are shown as substantially cylindrical, are mounted within saidguides post. 4 and frame 1 Uiv vhandle 27 and herein gives the cured' 'nthe recesses G of the window frames, to a drum 26, of similar member,provided with a suitable handle 27, and secured, for instance,conveniently to the car body.

"When it is desired to clean the glass of rain, snow, sleet o1' thelike, one rasps the rum 26 a half turn and thereby moves the cleaneracross the glass eflectually cleaning the same. The next time it isdesired to clean the glass the cleaner may be moved back to its formerposition in the same manner or', of course, the cleaner may be movedacross the glass asmany times as desired.. r)The drum may be inclosed ina suitable case'28, if desired, provided With Aan opening 29 to receivethe handle 27,

Our improved cleaner combines the ad vantages of simplicity ofconstruction with certainty of operation. The cleaner being securelyheld at both ends by the carriers, in position against the glass, isalways pressed against the glass with sufficient pressure to cause it toremove the moisture more e'ectual/ly than would be the case if it wereheld against the glass' by spring pressure only. The slots intbe guides2, 3, being 'on the lower side f said guides cannot become filled withl'snow and ice and the cleaner thereby rendered useless.

Doubtless modifications of the foregoing construction may be devised,for accomniishing the same pur ose, Without departing trom the spiritanscope of our invention.

Claimsz 11, A Window cleaning device comprising a laterally operativecleaning member, 'a

vback member secured thereto, carriers, hori zontal concealed tracks forsaid carriers,
